MURPHY COMPANY, OF NEWKENSINGTON, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA CAR ROOFApplication filed November 21, 1930. Serial No. 497,099.

This invention relates principallyto flexible car roofs of thekindwherein the metal roof sheets are connected by seam caps that extendfrom eaves to eaves of the car and consist of intermediate and endsections arranged end to end in overlapped relation so that said capsare applicable to cars of different width. It is the object of thepresent invention to prevent leakage between the ridge ends of the endsections of the seam caps. The invention consists in the sectional seamcap and in the arrangements and combinations of parts hereinafterdescribed and claimed.

In the accompanyin drawings, which form part of this speciflcation andwherein like symbols refer to like parts wherever they occur,

Fig. 8 isa perspective View of the ridge end portion of one of the endsections of a seam cap; and i Fig. 9 is a sectional perspective view ofa'portion of the ridge or intermediate section of a seam cap, thesection being taken midway of the ends of said section.

Referring to the accompanying drawings, my invention is shown inconnection with a l1 that bear 'flatwise on the upwardly incarline tocarline and are bolted or other-' wise removably secured to the topflanges 2 of the side plates A. The roof sheets are supported betweenside plates by a ridge pole 4c and purlins 5 which extend longitudinallyof the car beneath the carlines and are bolted to the base flanges 1thereof. The roof sheets C have raised side marginal panels 6 that areinclined upwardly and terminate in upstanding side marginal seam flanges7 that extend from end to end of said sheets. The roof sheets are alsoprovided at their eaves ends with depending flanges 8 which overhang thewebs of the side plates and terminate in inturned portions 9 thatarespaced away from said webs.

Weatherprooflng members in the form of inverted channelshaped seam capsD straddie the carlines B and the side marginal flanges 7 of adjacentroof sheets with their webs bearing flatwise against the webs of thecarlines and are rigidly secured thereto adjacent to the ridge andtheeaves by rivets 10. The channel-shaped seam caps D are provided withoutstanding base flanges olined side marginal panels 6 of the roofsheets, thereby holding said sheets down on the car. 'The eaves endportions of the seam caps are provided with depending eaves flanges 12which overhang and are. spaced.

from the ends of the carlines and the eaves corners of ad acent roofsheets and terminate in inturned portions 13 that are spaced away fromthe inturned ends 9 of the ver- 'tical webs of the side plates.

Running boards 14 extend longitudinally of the car at the ridge and aresupported on the lateral top flanges of Z-bar running board saddles 15whose lateral base flanges rest on the seam caps and are rigidly securedthereto by the rivets 10 that secure the ridge portions of said caps tothe carlines.

The transverse seam caps D are made of a plurality of sections arrangedend to end in overlapped relation so that said caps are applicable tocars of different widths. As shown in the drawings, said seam caps arepreferably made in three sections: namely, duplicate end members orsections 16, which extend from eaves to points adjacent to the ridge,and a single intermediate or ridge section 17, which overlaps the ridgeend portions of the two end sections. The ridge sections 17 of the seamcaps D are preferably pressed outwardly adjacent to each end, as at 18,to provide a space between the overlapped portions of the ridge and endsections for strips of tar paper or other suitable material 19, which isdipped in paint before application. This arrangement provides awatertight joint between the overlapping ends of the cap sections.

In order to prevent leakage between the ridge ends of the end sections16 of each seam cap D, the ridge end portions of the base flanges ofsaid end sections are cut away or notched, as at 20, and the ridge orintermediate seam cap section 17 has its base flanges depressed, as at21, to rest upon the side marginal roof sheet panels '6 within thenotched ends of the base flanges of said end cap sections. By thisarrangement, the base flanges of the ridge or intermediate cap section17 of the seam cap bear flatwise upon the roof sheet panels 6 oppositethe space between the end cap sections 16, thereby preventing water fromentering the seam cap at points opposite the ridge ends of the end capsections and being blown over the flange 7 of the roof sheets into theinterior of the car. Although small spaces are left between the ends ofdepressed panels 21 and adjacent edges of the notches 20, it is notedthat these openings are located opposite the end cap sections 16,instead of being located directly opposite the space between the ridgeends thereof, whereby said. end cap sections serve as baffles to preventany water that enters these holes from reaching the roof sheet flangesand being forced thereover into the interior of the car.

The invention is not restricted to the precise forms and arrangementsshown and described. 1

What is claimed is: V

1. A seam cap fora car roof, said cap com prising end and intermediatesections provided with outstanding base flanges, the adjacent ends ofthe base flanges of said end sections being provided with notches, the

base flanges of said intermediate cap section being provided withdepressed portions adapted to seat within the notches in the baseflanges of said end cap sections.

2. A transverse seam cap for a car roof, said cap comprising endsections and a ridge section overlapping the ridge ends of said endsections, said sections being of inverted channel-shaped cross-sectionwith outstanding base flanges at the lower edges of their side Walls,the ridge ends of the base flanges of said end sections being providedwith notches, and the base flanges of the ridge section being providedwith depressed panel portions adapted to fit within the notches in thebase flangesof said end sections.

3. A seam cap for a car roof comprising end sections and an intermediatesection overlapping the adjacent ends of said end sections, saidsections being provided with '1 outstanding base flanges, the adjacentends of the base flanges of the end sections being provided withnotches, and the base flanges of the intermediate section being providedwith depressed panels adapted to cooperate with the notches in the baseflanges of said end sections.

4. A seam cap for a car roof, said caps comprising end sectionsconnected by an intermediate section adapted to overlap the adjacentends of said end sections, said sections being provided with oustandingbase flanges, the base flanges of the intermediate section beingprovided opposite the adjacent ends of said end sections with portionsdisposed in the plane of the base flanges-of the end sections beyond theouter edges thereof.

5. A car roof comprising roof sheets provided along their adjacentmargins with upturned flanges, and seam caps straddling the flanges ofadjacent sheets, each of said seam caps comprising end sections providedwith outstanding base flanges that rest upon adjacent sheets, and anintermediate section overlapping the adjacent ends of said end sectionsand provided with outstanding base flanges overhanging the base flangesof said end sections, the adjacent ends of the base flanges 'of the endsections being provided with notches, and the base flanges-of saidintermediate section being provided with depressed panels that fitwithin the notches in the base flanges of the end cap sections and bearupon adjacent roof sheets.

6. A car roof comprising roof sheets extending from eaves to eaves ofthe car and having upturned. flanges at their side edges,

and seam caps extending from eaves to eaves of the car and straddlingthe side marginal portions of adjacent sheets, each of said seam capsconsisting -oil? end sections of inverted channel-shaped cross-sectionwith outstanding base flanges that bear flatwise on the side marginalportions of adjacent sheets and are cutaway at the ridge ends of saidsections, and a ridge section of inverted channel-shaped cross-sectionwith onstanding base flanges, said ridge section overlapping the ridgeends of said end sections and having depressed panels in its baseflanges that fit within the cutaway ridge ends of the base flanges ofsaid end sections and bear upon the. side marginal portions of adjacentsheets.
